Current User Account - Business Rule

Hi,

I am trying to create a business rule that 'hides elements' based upon the 'current user account' as below. I interpreted this variable as the account that the current user's 'Contact' is assigned to. Is this correct? I can't seem to get it to work as intended.

I have added myself as a contact to an account as below.

Is there any way to set up a business rule to show/hide or set read/write permissions based upon whether the current user is assigned to an account?

Thanks in advance,

Brendon
